Doing some work at the moment so I haven't read all the posts mainly just the first page.
In my experience this combo is pretty much one of my favorites. I've only done it 4 times keeping it to 1-2 tabs of above average blotter, about 3-5grams of standard cubes and .5-.7 of pretty clean molly. If you can get your hands on it I'd definitely suggest getting some molly. I'm not one for pills mostly because you just don't know what's in em.
It's a pretty flooring experience so don't expect to be partying or doing anything to wild. I went to a show on my first trip of this sorts with a tab 2grams of cubes and a .9 of some good molly. That was pretty fun. Really depends on the person though, a friend of mine lost his shit while I was coming up but came to midway through the peak.
As far as timings:
0:00 Acid
0:15 Start Eating the shrooms
1:00-45 Down some Molly (See how you feel about one, you may be content with just the two prior ones, besides you can always save it for later :D)
Generally midway through I like to redose on the Molly a small amount, generally a third or half of what I initially took is good. A good thing to keep in mind is not to completely overdo it and just take a bunch of shit at once. The comeup is/can be a bit of annoyance.
As far as another combo worth trying I'd definitely have to agree with everyone who's said LSD+MDMA+Ketamine. It's pretty much my favorite combo, hands down. It's like finding heaven and then being able to hold it, swim in it, and dance with it for 8 hours. Literally loads of fun, and quite eye opening. Best of luck and be safe.
Cheers!
